SPECIFICATION forming part of Letters Patent No. 630,247,6.ated August 1, 1899. Application filed May 25, 1899. Serial No. 718,154. (No model.)

Be it known thatwe, VILLIAM Il. Lol and JOHN M. Gnoien, citizens ofthe United States, residing at Victor, in the county of Iowa and State of Iowa., have invented new and useful Improvements in Creaming-Cans,of which the following is a specification.

Our present invention relates to certain improvements in elearning-cans, and has for its object to provide a device of this character which will be extremely simple in construction, cheap of manufacture, and easy and effective in operation.

It is one of the essential features of the invention to provide a crea1ning-can wherein the interior parte may he quickly and easily removed for the purpose of cleansing such parts.

The invention further comprises means for preventing eddying or whirling of the liquid during the operation of drawing off the contents of the can.

The invention comprises other features of construction and arrangements of parts hereinaf ter to be described in detail and then more delinitcly pointed out in the claims which conclude this specification.

In order to enable others skilled in the art to understand, make, and use our said invention, we will describe the same in detail, reference being had for this purpose to the accompanying drawings, wherein- Figure l isa vertical central section of a` creaniing-can constructed in accordance with our invention. Fig. 2 is a perspective view of the conducting-tube. FigY 3 is a modified arrangement el' coinlucting-iube.

Referring to the drawings, the referencenumeral l designates a can or vessel, which is shown as being tapered in forni; but we wish it to be understood that we do not confine ourselves to any particular shape orform of can or vessel. 'lhe said can or vessel is provided near its lower end with a conical bottom 2, thc sides of which are of comparatively steep pitch and the apex of which is disposed centrally within the can and directed upward toward the top thereof. The upper open end of the can or vessel is closed by a removable top or cover 2S of conical shape, and fixed to the apex` of said conical top is a funnelanoinh -1. having a strainer 5 removv ably seated therein. In practice we prefer te form an annular groove 6 in the funnel mouth i, in which the rim of the strainer rests or is seated, and we 1nav,if desired, empleysoine suitable fastening means for sc- -eurely holding the strainer within 'the annular groove 6, although this is not thought to be essential. The said cover is further pre vided on its under side, at the apex thereof, with a depending tube 7, which extends a slight distance down within the can or vessel.

The reference-numoral S indicates a conn duetortube, the upper end of which when in position for operation telescopes over the lower end of the depending tube 7 on the cover 3. rl`he lower end of the said conductor-tube is ared outward in the form of a cone 9, and the extreme lower edge of said concis crimped or corrugated, as at 10, around its entire circumference to providea plurality v of gaps or outlet-openings for the passage ofv the iluid from the conductol-tube into the can or vessel, and this crimped or corrugated edge we consider to be an important feature of the invention, since it acts during oper ation to forcibly distribute the water through the milk, so as to causo a rapid separation and ascent of the cream.

In order to prevent cddying or whirling o f the fluid within the can or vessel during the operation of drawing oil' the water and thin milk, which eddying or whirling would tend to mix the cream withthc other fluid, we have provided the conductor-tube S with. two or more lateral wings or blades 1l which extend from a point near the lop of the tube to a point adjacent to the corrugations or erimps in the cone 9. \Vhcn the conductor-tube is in position for operation, it will be seen that theextremclower-corrugated edge of the cone 9 rests or seats in the annular groove formed between the conical bottom 2 and sides or' the can, as clearly shown in Fig. l of the drawings.

The can or vessel is provided at the lowest point adjacent to the bottom with a draw-off cock or faucet li', and above said faucet is a sight tube or gage lll, which will indicate the level of the liquid within the can er vessel; The can is further provided with suitable handles 111-, as usual.

In Fig. 3 of the drawings we have shown a .Y the form of a thin moditied form'of conductor-tube, in which instance the l ower conical end 15 thereof is made adjustable or distensible in order that it may be tted to vessels of different size. The said conical end 15 is split along the line 16 and the edges made to overlap in order to accommodate for adjustments, the parts being he1d secure when adjusted to the proper size by means of a set-screw 17. By this construction it will be seen that the conical end of the conducto1-tube,may be applied to vessels of different size, of said tube has a telcscoping connection with the depending tube on the top or cover it will be understood that the conductor-tube will also be suited to cans or vessels of different heights. This construction and adjustment of the parts, whereby they are suited to cans or vessels of diterent sizes, is considered to be an important and desirable feature of theinvention.

The operation of the invention may be briefly stated as follows: The milk having been first placed within the can either by pouring through the conductor-tube or otherwise, water of a comparatively low degree of temperature is then introduced through the conductor-tube, (it being understood that the part-s are in the position indicated in Fig. 1,) and passing down the latter it strikes the conical bottom and enters between the latter and the conical end of the conductor-tube in sheet or lm, and continuing in its course it is forced by pressure upward through the gaps formed by the corrugations or crimps in the said conical end of the conductor-tube, by which the said thin sheet or film is divided into narrow streams, which Hush the inner surface of the can and are also distributed through the entire body of milk, thus causing a rapid separation'and formation of the cream, which latter, owing to its specic gravity being less than that of 'the water, quickly rises to the top. The liquid is allowed to remain at rest for a few moments, and then the water and thin or blue milk are drawn on through the cock or faucet, after which the cream may be remove-"I in a similar' manner.

It will be seen that all the interior parts of the device are removable and separable, and they can thus be cleansed with facility, thus insuring the sweetness of the milk and cream.

A practical test of the device has demonstrated that cream can be separated from milk in from three to five minutes.

That we claim, and desire to secure by Letters Patent, is-
